Amethyst brings in a spiritual lightness to their endeavors and helps them to achieve greater balance in their lives. It helps them channel their ambition in a healthy way. 
Carnelian matches Aries fiery energy because it is a fire stone. So, if Aries feels as though they are losing their fire, they can use this stone to reignite the flame. It brings passion and courage at a time when they might be feeling defeated.
Clear Quartz brings a calmness to the passionate and ambitious nature of Aries so that they don’t forget to consider others as they forge ahead to achieve their goals.
